Weiss Industrial Thermometer | A7VU9-120 | 0-120°F & °C | 7″ Scale
Product Description
The A7VU9-120 offers a compact 7-inch (175 mm) scale while maintaining the full functionality of the larger industrial models. With a temperature range of 0-120°F (-17 to 49°C), it is perfectly tuned for the UAE’s district cooling and building management sectors, specifically for chilled water supply and return lines.
Despite its smaller profile, it features the robust Vari-angle design, allowing the thermometer to be tilted and rotated to any position for optimal viewing. The case is constructed from GE Valox® polyester, ensuring it can withstand the high-ambient temperatures and humidity often found in mechanical plant rooms across Dubai and Abu Dhabi.
Key Features
- Compact 7″ Scale: Ideal for installations with restricted head space or on smaller equipment skids without sacrificing readability.
- Vari-angle Adjustability: The flexible mounting allows the head to be positioned at any angle, eliminating the need for separate straight or 90-degree models.
- Dual Scale Display: Simultaneously provides readings in Fahrenheit and Celsius, catering to international project requirements in the UAE.
- Non-Mercury Filling: Utilizes a high-visibility blue spirit liquid, offering a safe and environmentally friendly alternative with $\pm$1% accuracy.
- Durable Construction: The high-impact GE Valox® housing is corrosion-resistant and provides excellent protection for the glass sensing element.
